This file contains two technical diagrams showing details of a bypass system for Orwell Dam. Figure 1 is a cross-sectional engineering drawing of the control structure that shows key measurements, including a 43ft distance from the control structure bottom to dam top and 15ft water depth requirement for submersible pumps. Figure 2 is an aerial photo showing the 2003 bypass system layout, with clearly marked locations for bulkhead, pump placement, piping routes (shown in orange), and generator positioning. The image includes annotations for piping paths, pump locations, and generator/wiring placement, with a note indicating locations are approximate and will be field-verified.

These diagrams appear to be supporting technical attachments for a solicitation related to dewatering maintenance at Orwell Dam, providing contractors with visual references for the bypass system setup, measurements, and past implementation examples. The drawings give critical spatial and engineering context for the 80 cubic feet per second (cfs) bypass flow requirement specified in the associated contract opportunity.
